Heres a pic. of Great & Junk collected WVO.

The emty cubbie on the right is pristien WVO Canola (cola in color). Notice there is NO SCUM film on the cubbie (cubbie sides drain to clear in mins).. The oil came from a food manufacture plant. No fat/lard/wax/grease. The oil is used in a 1000 gal. fryer with a great filter. I still filter the oil but find VERY VERY little debri in my 5 micron filter.

The cubbie on the left is junk WVO. One third is fat/lard/wax/grease..
Notice the SCUM(yellow line) on the top of the junk WVO cubbie. The cubbie has been in my garage for 3 weeks. The scum film line is still there after 3 WEEKS in a 70 to 80 deg. garage!!!

I feel almost all WVO problems are do to JUNK WVO leaving a scum film on filters & tanks..thus clogging the fuel system in one way or another.

Theres no way that junk WVO with SCUM is going in my car. Its not worth it!
I guess what im saying is even after the top part of the junk WVO has been filtered... its still SCUM WVO. Just my 2 cents.

Starting with good oil will save many headaches. If I did not have access to good oil I would run a two tank system to preserve the original fuel system as much as possible.

You're right. That's CRAP!

The tallow is a high energy fuel. It has IIRC more energy than petroleum diesel.
The only thing it lacks is liquidity, and that can be added using heat.
If heated and filtered and then (while still liquid) added to the heated feul tank, it can pass thru the heated fuel line and heated filter to the fuel c/o valve and then to the IP.

I am NOT joking, this stuff really works well, is ULTRA STABLE (very low polymerisation) and smells like a BBQ on wheels. (where canola smells more like a deep fryer on wheels)

So far I only have one WVO source and I consider it good. Most of what I get looks like that of your "good" cubbie. But they also give me some crap. This is because they simply give me everything they drain weekly in the original 5 gallon pails. So my first step is always to separate the good from the bad. If it looks like Pepsi on top it goes in the "good" stack, and if it looks like gravy it goes with the "bad".

Then, settling becomes your best friend. Eventually, the "Crap" has some good stuff that floats to the top, which I slowly siphon off until the gravy appears. Then, I pour all the leftover "gravy" into one big pail, and let it re-settle. And so on.

Then I take my good stuff and filter it like mad- first through cheesecloth, then through a triple paint-strainer, and finally at least one pass slowly dripping through a home-made toilet paper roll filter. This is finally tested by pouring the finished product through a fine mesh funnel strainer. If the funnel blocks up, or if I feel any grit on the strainer when it's done flowing, then I drip it through the toilet paper again.

I end up with a clear dark amber canola, which I mix 5 parts with 1 part Naptha camp stove fuel. Then this mixture gets blended in my tank with Diesel fuel- right now about 2 parts Diesel to one part WVO. When the hot summer sets in, I will try 50:50. This is my first year using WVO, so I'm still experimenting. I may do a heated tank conversion for fall and winter, but I'm more inclined to use my WVO in the furnace tank- that's where I really need the fuel savings- and run the Benz on straight Diesel in the winter.

If I understand correctly, a heated WVO setup will compensate for more viscous oils.

Regarding either the "high quality" WVO (that's liquid at room temperature) or the "low quality" WVO (that's more like gravy at room temperature), how are other disolved materials handled? Common restaraunt solids like sugar, salt, dish soap & water, etc?

How does somebody know what else is in there, besides VWO?

Coldwar,

Tell me more about using WVO as heating fuel.

Are you using it in a standard high pressure (100psi) oil burner? Do you mix it with fuel oil, what ratio?

P E H

Patrick,
If there are dissolved sugars in the WVO, they do not seem to cause any issues. My Used Cooking Oil is prefiltered to 5 micron before setting aside as fuel. As my source puts it straight into sealed buckets for me, and nothing other than fryer oil goes into the buckets, I do not need to dewater.

If you have oil with contaminants like water, detergents, etc, you may need to filter, wash and dry the oil before use.

Haven't done it yet. It's just something I'm considering. My burner is a standard unit, about 20 years old, so I'm thinking if I ruin it by using blend- not a real big deal. However, I definately plan on doing my homework. For the time being, my reasoning is that if I am successfully blending WVO and Diesel in my car with excellent results so far (about a month running 20-30% WVO, daily driving a 70 mile commute), I should also be able to use a similar blend in the furnace.

To get really serious about this, I should put aside the money I'm saving, say 30% of my Diesel fuel costs, and save it toward either a dual tank conversion for the car, a WVO-friendly home heating unit, or both.

Dave

The simplest way to heat you'r home using WVO is to buy a waste oil burning furnace.These are designed to burn used motor oil without any kind of oil preheating nessasary.They are designed with a larger and more durable fuel pump,and a larger spray nozzel to prevent plugging.Older oil furnaces could probably burn straight WVO after settleing and filtering if you'r fuel tank is indoors.You might have to try a couple different nozzel sizes and adjust the air supply though.But I wouldn't recomend trying WVO in a newer high effiency furnace.I do know that there are people burning 100% biodiesel in both types with no problems except replacing some rubber gaskets etc.

I think the rubber gaskets you are talking about are the ones located in the pump. From what I've been told that [replacing seals] will be a constant battle.

The member that mentioned the used motor oil is on the right track. I think that type of furnace will burn WVO with no problems.

Cheers,

Bill

Their is a Yahoo Group mail list that is dedicated to veg. oil /waste oil fuel heaters. Sorry I don't have the link infront of me. Someone will pipe in and link it here or do a search in Yahoo groups.

I was sent a message asking about furnaces certified for residential use.I don't know if any of the forced air units are for home use or not.But I do know that if you do an internet search on waste oil boilers or wood boilers with waste oil backup you will find boilers that should have no problem burning WVO as long as the tank is indoors where it's warm.www.wasteoilburners.us has furnace and boiler conversions available for both comercial and home use.
